I got two K32-SU3 Rev.2 from Amazon 08-09-17 (ser #: I17030622 and I17030623) to be used on Win10 Home. One with a Seagate ST500DM000 5tb drive and the other with a Toshiba MD04ACA500 5tb drive, both known good.

After install of drives in the enclosures, connection to pc and power I get nothing, no power lamps, pc does not see them (obviously w/o power). Any clue on what the problem could be? Drives worked in old enclosures that I no longer have. Power bar I'm using works fine, that's a known.

I did same thing as you did, I just bought the enclosure from amazon, it arrived today 8/9/17 and I have same problem? My laptop And Desktop recognize it, but I cant access it and the drive light goes out after computer boots up?
